SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating at 210°C and on burning. This produces toxic and corrosive gases including nitrogen oxides. Reacts with bases, strong acids and strong oxidants.
Chemical stability
Shelf life of the 80 w formulation is more than 2 yr
Possibility of hazardous reactions
NonflammableDIPHENAMID is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). This compound is decomposed by strong base or acid.
Conditions to avoid
no data available
Incompatible materials
Incompatible with highly alkaline materials.
Hazardous decomposition products
When heated to decomposition it emits toxic fumes of oxides of nitrogen.

- Toxicity to microorganisms: no data available
Persistence and degradability
Microorganisms appear to play a significant role in degradation of diphenamid in soil. certain species of soil fungi are capable of metabolizing diphenamid in vitro.
Bioaccumulative potential
The bioconcentration factor (BCF) for diphenamid in aquatic organisms has been estimated to be 27(1). The low BCF value indicates that diphenamid would not be expected to bioconcentrate in aquatic organisms(1,SRC).
Mobility in soil
Diphenamid is not tightly adsorbed on soil colloids. it leaches rapidly in sandysoils but slowly in loam or clay soils. in sandy soils, retention of an effective concn in the weed seed germination zone with heavy rainfall can be a problem.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
